FLUID-VALVE LOCK.

Application filed June 17, 1922. Serial No. 569,os1.

To all whom it may concern:

Be it known that I, ALBERT B. HAMILTON,

a citizen of the United States, residing at 308 th Street SXV., Washington, District 5 of Columbia, have inventedcertain new and useful Improvements in Fluid-Valve Looks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to controlling devices and more particularly to permutation looking devices for fuel lines of motor vehicles. v

The principal object of the invention is to provide simple and eflicient mechanism whereby the passage of fuel, whether in liquid or vaporized form to the engine may be cut ofi' so that unauthorized use of the machine is efi'ectively prevented.

%i Many permutation valves have been designed and some I believe have been e1n-, ployed in substantially the same relation as is eontemplated here, but to my knowledge all of them have been of such Construction that their use was prohibited either by reason of their eXcessive cost or their inability to efl'ectively perform the function for which they were designed. It is there'fore another object of this invention to provide a simple and efficient devicewhich can be installed readily at a nomical cost and which will effectively prevent the unauthorized use of the car irrespective of whether the ignition system can be operated or not.

Still another object of the invention is to provide an improved type of permutation valve which is cheaply constructed and therefore accessible to all motorists and which can be readily repaired and parts replaced conveniently and at small eXpense.

The convenience of operation and further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings which form a part of this invention, and in which:

Figure 1 is a detailed elevation of a motor vehicle with parts removed and parts in section to clearly illustrate the application of the invention;

Figure 2 is a top plan View of the parts shown in Fig. 1;

Figure 3 is an' enlarged sectional view taken through the valve employed in Fig. 1;

Figure 4: is a detailed elevation of the valve when viewed at right angles to the position shown in Fig. 3;

Figure 5 is a detailed top plan View of the dial and combined controlling and indicator hands;

Figure 6 is a detailed plan View of one of the .valve disks; i Figure 7 is a detailed sectional view of the controlling mechanism.

Referring more particularly to Figs. 1' to 7, 1 represents the engine of a notor vehicle, having as is usual an intake manifold 2 connected to the engine at one end and to the carburetor 3 at its opposite end; The carburetor is connected to the supply tank 1 by pipe 5 as is usual and located'within the pipe is the permutation valve which forms a part of my invention. .As shown in Fig. 1, this valve is controlled and operated from mechanism generally indicated at M upon therinstrument board 6 of the automobile and connected to the valve by rods 7 and 8. This valve comprises a housing or casng 9 having located upon one disk an inlet nipple 10 to which the pipe 5 is connected. The

opposite, side of the casing is provided with an outlet nipple 11 also connected to a' part of the fuel tube 5 which leads into the carburetor 3. r

Projecting upwardly from the base of the casing i's a central stud 12 having a recess or socket 13 formed in its upper end and adapted to receive the lower end of a shaft 14 rotatably mounted therein and carrying a valve disk generally indicated at 15 which is adapted to control the inlet of fuel through the nipple lo.

surrounding the shaft 1 1 and rotatably mounted thereon is a sleeve 16 which has keyed thereto a disk 17 similar to the disk 15 and which is adapted to control the outlet of fuel through the passage nipple 11.

The upper end of the casing is closed by a screw threaded cap 18 having a packing `gland 19 thereon which is engaged by the packing nut 20. This gland effectively prevents the escape of any fuel around the sleeve 16, while a similar packing gland 21 carried by the upper end of the sleeve effectively prevcnts any escapeof fuel around the shaft 14.

In the Construction shown in Fig. 3 the valve is adapted to be connected to the floor boards or other suitable support by means ot' the bolt receiving cars with the shatt and sleeve H and 16 projecting above the floor boards in position to be rotated a:: will be hereiua'tter described when it is doired to control the position ot' the valve 'desi 15 and l?.

hen used in this manner there is a dial surrounding the shat't and rigiclly mounted with respect to the casin over which is aclapted to trarel the valve controlling and indicating fingers 2 and These fingers are respectivcly Secured b et screws 26 and 2? to the sleeve 18 and shatt le and the tormer finger 24: has a vertical and horizontal extension in the 'form of pointer 28 operating over the dial.

hen the J'alve is to he operated from the das board as shown in Fig. l, the Operating arms 24 and 25 are in the nature of levers and are connected to the Operating mechanisni through the rods and 8 which are connected by universal joints with the arms fli and 25 and with similar arms 29 and 30 to be hcreina'tter described.

Each valve disk 15 or 17 comprises a fiat d sk having an annular flange 32 around its outer marginal edge. which fiange is provided with au opening adapted to registcreither with the port in the nipple 10 or the port in the nipple 11 as will be readily understood. he structure f the valve is lightened considerable by providing openings 34 which also serve aspassagewa s between the twovalve which contact with one another' as shown in Fig. 3,`one having a depending iange and the other having an upstanding flange with the disk bodies in contact.

Each disk is also provided with a flexible band-like washer 35 eXtending around and secured to the fiange in any suitable inanner. This Washer is provided to' insure tight engagement between the disks and the casing, and is preferably made removable in any suitable manner so that they may be reuewed when worn. it will be noticed in this co'nection that in order to renew' the washers all that is necessary is to remove the cap 18 and pull out both valves simultaneously. Alter their washers have been replaced they can he again placed in the casing and secured by siinply screwing the cap 18 hack in place.

ln the *form shown in Figs. l and 2 the shai t 14( and sleeve 16 are pro *ided with lever arms 33 and 37 corresponding to the parts %and 25 but having connected to their terminal ends hy universal jonts 38 the Operating rods 7 and' 8 which' are in turn respectively connected by universal joints 39 to the levers 29 and 30. These levers as shown are Secured by means of set screws 40 tothe sleeve 43 and shaft 42 jour- `I dishe naled in the housing 43. The sleeve is journaled directly in the housing and the shaft 42 journaled in the sleeve as will be seen froni an inspection of Fig. 7. The upper end of the sleeve 41 has secured thereto a combined indicating and operating linger 2 1- and the shaft has secure-d thereto a combined indicating and Operating finger 25, both adapted to operate over a dial 23.

En the forms shown in Figs. 1 and 2 the lock valve is located in the tuel line in advance ot' the carburetor 3 as is shown, but i wish it understood, however, that the opting niechanism li may be located at any point. 'even below the floor boards and exposed through an opening therein which iii-ay be covered in any suitable manner.

ln the operation of the device we will say. that the port 233 ot' the lower disk 15 is in register with the inlet nipple 10 and that i t 'l e port ot the upper disk 17 is in regis- 'er with the outlet nipple 11. The set and 2. or those indicatcd at 26' and 27' may be looseued and the indicating and Operating hands set on any given comhinaton ot numbers such as 1 and l as shown in Fig. 5, and the set screws then ightened. (hen the operator wishes to och his car against unauthorized use he sim- ;ly inovcs either the finger 24 or the finger of the valve disk out of re ister with its inlet or outlet opening. He may if desired move both fingers so that the ports 33 ot both dislts are out of re ister with their respective 'openings in the casing. In either event anyone atteinpting to use the autoinohile without knowing the eombination would be prevented 'from doing so by reason of the fact that no 'fuel could be earried to the engine. If only one hand were set by the owner of the vehicle and an unauthorized person attempted to use the vehicle it would be possible 'for him to operate the wrong hand and thus cause an additional lock to he placed against the passage of fuel, the operation of either valve eitectually cutting of? fue] to tae engine. If at any time the operator desires to change the combinatiou he may loosen one of the set screws 26 or 27 or their equivalent on the Operating mechanisnn 26' and 27'; move the Operating hands 24 and 26' around the sleeve or sha'ft until the pointer points to the number or numbers which will constitute the new combnation. Any change in the combination ,is of course made when the valve is in open position.

?While I have described my invention as appiied to permutation valves for controlling and looking the uel lines of motor vehicles it Will, ot' course, be understood that such mechanism can be readily applied to the control of other fluid lines such as gas, or watersupply systems wherever used..
